@Carl Thank you for the extensive play-testing, taking of screenshots, and writing you've done lately to update your wonderful guides.
The Fertilizer Guide is really great. How disappointing (for me) that fish freshness influences fertilizing effectiveness! So hard to keep fish fresh!
At the very bottom of the page, you write as follows:
GROWFRUIT, BEE BOXES AND FUNGAL INFUSION (HERMIT)
Growfruit (from the Spring Challenge) are the only plant that gets a 'high' fertilizer grade score. They are available by cheating (bb.showhiddenobjects).
I think it's worth mentioning that growfruit can also also be purchased from the kiosk in Granite Falls' Campground area.
Again, thanks for all the new guides you've created recently! I'm loving the video guides, too.
